lsvdiskmember
Use the lsvdiskmember command to display a list of MDisks that are members of the specified volume.
Syntax
>>- lsvdiskmember -- --+--------------------+-- ----------------> '- -copy -- copy_id -' >--+----------+-- --+-----------------------+-- ----------------> '- -nohdr -' '- -delim -- delimiter -' >--+- vdisk_id ---+-------------------------------------------->< '- vdisk_name -'
Parameters
- -copy copy_id
- (Optional) Displays a list of MDisks that are members of the specified volume copy.
- -nohdr
- (Optional) By default, headings are displayed for each column
of data in a concise style view, and for each item of data in a detailed
style view. The -nohdr parameter suppresses the
display of these headings.Note: If there is no data to be displayed, headings are not displayed.
- -delim delimiter
- (Optional) By default in a concise view, all columns of data are space-separated. The width of each column is set to the maximum possible width of each item of data. In a detailed view, each item of data has its own row, and if the headers are displayed, the data is separated from the header by a space. The -delim parameter overrides this behavior. Valid input for the -delim parameter is a one-byte character. If you enter -delim : on the command line, the colon character (:) separates all items of data in a concise view; for example, the spacing of columns does not occur. In a detailed view, the data is separated from its header by the specified delimiter.
- vdisk_id | vdisk_name
- (Required) Identifies the specific volume to query..
Description
This command displays a list of managed disks, which provide extents that make up the volume that is specified by the ID.
Every volume is constructed from one or more MDisks. At times, you might have to determine the relationship between the two objects. The following procedure allows you to determine the relationships.
If you use the lsmdiskmember command, the concise view displays a list of volumes. These are the volumes that are using extents on the managed disk that is specified by the ID. The list displays the members of the respective object and is independent of the state of the individual members; that is, if they are in offline state, they are still displayed.
lsvdiskmember vdisk_id | vdisk_name
where vdisk_id | vdisk_name is the name or ID of the volume. This displays a list of IDs that correspond to the MDisks that make up the volume.lsvdiskextent vdisk_id | vdisk_name
where vdisk_id | vdisk_name is the name or ID of the volume. This displays a table of MDisk IDs and the corresponding number of extents that each MDisk provides as storage for the specified volume.lsmdiskmember mdisk_id | mdisk_name
where mdisk_id | mdisk_name is the name or ID of the MDisk. This displays a list of IDs that correspond to the volumes that are using this MDisk.lsmdiskextent mdisk_id | mdisk_name
where mdisk_id | mdisk_name is the name or ID of the MDisk. This displays a table of volume IDs and the corresponding number of extents that are used by each volume.An invocation example
lsvdiskmember 1
The resulting output:
